"Good teams win promotion and I thought we were unified in what we did," said the City Ground boss after the 1-0 defeat by Carlisle.
"The experience that we have had - and the disappointments - will be useful.
"We do not want those disappointments to grow. But we have a good group here. I am confident that we will still achieve our objectives this season.
"I will take that (level of performance) again, because that will win games. We have got to be top-class now. There is no margin for too many errors from this point in. But we can do it."
